How to do a IP NetMask access rule
We have two use case where that kind of rule is inthresting...
The first one: We have have two domain one in dmz and one internal. If we could make access rule to allow only the internal netmask that will hide in the portal all web site that could not be accessed from internet because there are not exposed in dmz. User will stop calling you saying why i can access those application...
The second one is more tricky, we have users who suppose to have access to an application only when they are one specific computer. Those computer are in isolated vlan to avoid information leak by email or other method... Currently we make a deny in nginx but that the same issue of case 1, the application is shown in portal and the best would be to hide when user not suppsoe to have access...
